Fairfax County is considering making all existing and future development built to lessen flooding risks from huge, 100-year event storms, as opposed to a 10-year storm.
The risk of flooding in the county is rising due to climate change, staff told the Fairfax County Board of Supervisors environmental committee late last month. While preventing flooding is impossible, its impact can be mitigated, they said.
Under the staff proposal, the county would require all future development to have proper drainage, pipe conveyance, and safety measures to accommodate a 100-year storm event adjusting for climate change.
